In 1611, Nicolas Vignau, a white scout, landed at what is now Portage du Fort with a party of Algonquins. On their way to tribal headquarters at Allumettes Island, they had to portage overland for the first of a series of five difficult cataracts.

In 1694, the famous military engineer Louis d'Ailleboust, Sieur de Coulonge, established a fur trading post hear the mouth of the Coulonge River. The stretch of cataracts that led to Fort Coulonge became known as "le portage du fort" and this is how the settlement at the foot of the rapids got its name.

Nicholas d'Ailleboust, Sieur de Coulonge, spent the winter of 1694-95 near the mouth of the Coulonge River and so established one of the first settlements on the Ottawa River.

The first trading post was called Fort-Coulonge. In 1760, the Northwest Company took over its management and in 1821, the Fort became the property of the Hudson's Bay Company. Until 1828, it served as the head post on the Ottawa River. The post's 655 acre farm was sold in 1844 and the buildings in 1855. The trading post became the village of Fort-Coulonge situated several kilometres down river.

One of the original five municipalities in Pontiac, Litchfield was erected on November 20, 1846, with Alfred Lancaster as its first mayor. In December of the following year, the first meeting of the district of the 3rd Division of Ottawa County was held at the home of Samuel Morehead on Highway 148. Today the house is the home of Dawson Morehead. In 1964 the Pontiac County Council (now Pontiac MRC) built its headquarters in Litchfield, on Highway 148 at the edge of Campbell's Bay.

--May 16, 2007The Pontiac Museum, which is located at the Fairgrounds in Shawville, and which is run by the volunteer Pontiac Historical Society, needs your help! The museum is housed in the former Shawville railway station, which was built in 1886 by the Pontiac Pacific Junction Railway. Home to the museum since 1976, the former station is now in need of repair.

The earliest settlers in the Shawville area were Irish Protestants from County Tipperary who came to Canada after the Napoleonic Wars ended in 1815. Many had first settled in the Carp Valley on the Upper Canada side of the Ottawa River. Local lore tells us that Thomas Hodgins, John Dale and his wife Elizabeth set out from this colony in the summer of 1821 to search for new land to settle. It is believed they paddled up the river, landing in a small bay some forty miles upriver. The two men then set off northward in search of a suitable place to homestead.

Lumbering and farming attracted the first settlers to Campbell’s Bay, which was incorporated as a municipality in 1904. E.H. Workman was the first mayor. The village was named after Lieut. Donald Campbell, a soldier in the Scottish Regiment, who was granted a large amount of land. The main drag, Front Street, is unique in that its buildings are on one side of the street only, giving everyone a majestic view of the Ottawa River.

The village of Bryson was named after the honorable John Bryson, MP for Pontiac. Incorporated in 1873, its first mayor was Walter Rimer.

Located on the banks of the Ottawa River, Bryson was an inland port for passengers and freight heading north-west-ward during the era of steamships. Near Bryson, there are ruins of an old grist mill. People came from as far away as Fort Coulonge to have their grain milled.

Located on the Ottawa River, Calumet Island was for many years the meeting place of the Algonquin people. During the French Régime, Calumet Island, like the rest of the Ottawa River, was a link in the western route to the Great Lakes (via the Mattawa River, Lake Nipissing and the French River up to the Georgian Bay).
